Résumé

Magnetocaloric cooling represents one of the most promising alternatives to vapour-compression. Despite that this technology has made substantial progress over last two decades, there are still unsolved challenges regarding the use of rare-earth materials, energy efficiency, and the competitive cost of potential future devices. State-of-the-art devices are based on the so-called Active Magnetic Regeneration, which is moderately efficient at low operating frequencies (up to 5 Hz). To achieve considerable cooling power and magnetic fields at such low frequencies, significant amounts of magnetocaloric and permanent magnet materials are required. A new research direction has emerged in recent years where researchers are trying to develop devices that operate efficiently at much higher frequencies (up to 50 Hz or more). We present a high-energy efficiency electro-permanent magnetic field source, which is able to oscillate relatively high magnetic fields without moving parts and at operating frequencies up to 50 Hz with energy efficiency above 80%.
